Crystal Spire
At Troop Lv 91, the Crystal Spire system will unlock. Crystal Spire will drop hero skin fragments and enhancement materials.
Rules:
-
Each day you can challenge multiple stages. Each challenge does not cost any challenge chances or stamina, but after a victory, all heroes who took part in that battle must sit out the remaining battles for the current layer. You can sweep Crystal Spire multiple times each day, the first 2 of which are free.
-
Defeat all the guardians to receive all the rewards for that layer. The higher up your progress, the more fabulous your rewards will be– but the enemies will also become more powerful.
-
You can try resetting stages to make changes to the order of your hero lineup. Participation chances reset daily at 05:00.
